Over two months, Wonsuk developed and expanded the next-engineer/next-java-exercise repository, delivering a modular Java curriculum and automating deployment workflows. He implemented core object-oriented assignments covering inheritance, abstraction, and design patterns, and stabilized the main branch through careful merge conflict resolution. Wonsuk introduced a deployment automation pipeline using GitHub Actions, Docker, and AWS ECS, enabling reliable CI/CD for Java applications. He also built extensible systems such as a strategy-based encoder, a modular calculator with robust error handling, and a coffee ordering platform leveraging enums and input validation. His work demonstrated depth in Java, CI/CD, and design pattern application.

Aug 1, 2025August 2025 monthly overview for next-engineer/next-java-exercise: Delivered a Deployment Automation Pipeline enabling reliable ECS deployments via GitHub Actions (checkout, Java setup, Gradle build, AWS credentials, ECR login, Docker image build/push, ECS task deployment). Introduced a Strategy-pattern Encoder with pluggable Base64, Hex, UTF-8, and EUC-KR encoders. Implemented Modular Calculator with core operations and division-by-zero handling, designed for easy extension. Added Coffee Ordering System using enums for type/size with validation and price calculation. Built Facade Pattern examples to simplify complex subsystems (home theater, startup).
